An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric, and isochoric. The curve which represents the adiabatic process among $$1,$$ $$2,$$ $$3$$ and $$4$$ is:

 1 $$4$$ 2 $$1$$ 3 $$2$$ 4 $$3$$

An ideal gas follows a process described by the equation $$PV^2=C$$ from the initial $$(P_1, V_1, T_1)$$ to final $$(P_2, V_2, T_2)$$ thermodynamics states, where $$C$$ is a constant. Then:
 1 $$\text{If}~P_1>P_2~\text{then}~T_1V_1~\text{then}~T_2>T_1$$ 3 $$\text{If}~V_2>V_1~\text{then}~T_2P_2~\text{then}~V_1>V_2$$

Two cylinders $$A$$ and $$B$$ of equal capacity are connected to each other via a stop cock. A contains an ideal gas at standard temperature and pressure. $$B$$ is completely evacuated. The entire system is thermally insulated. The stop cock is suddenly opened. The process is:
2. isochoric
3. isobaric
4. isothermal
